[Detailed description of the invention] (Industrial application field) The present invention relates to a prefabricated house having a lower roof.

(Conventional technology) An assembled house is a box-shaped housing unit of a certain size that can be transported, and the interior and exterior are finished. It is intended to be assembled into a house.

This type of prefabricated housing has been increasingly adopted in recent years because it has the characteristics of a short construction period and standardized housing with good dimensional accuracy.

Due to the manufacturing process, this prefabricated house is
As shown in Japanese Patent Application Laid-open No. 186297 and Japanese Patent Application Laid-open No. 60-40617, it is common that there is no lower roof.

(Problems to be Solved by the Invention) However, as demands for prefabricated houses have diversified, it has become necessary to provide a lower roof.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an assembled house having a lower house roof to which a lower house roof can be easily attached.

(Means for Solving the Problems) The present invention has been made in order to achieve the above-mentioned object by a distant relative. A roof fixing fitting is attached to the middle part of the front column of the housing unit on the upper floor, and a lower roof is provided which is fixed by the roof fixing fitting and the top of the column of the front row of the housing unit on the lower floor. be.

The roof fixing metal fittings used in the present invention may be attached to the pillars of the housing unit at the construction site, or they may be attached to the pillars of the housing unit in advance at a factory and transported to the construction site to form an assembled house.

(Function) In the present invention, since the housing unit on the upper floor is shifted backward and placed on the housing unit on the lower floor, the roof fixing bracket attached to the pillar on the upper floor and the top of the pillar on the lower floor are connected. The lower roof is fixed and installed.

By attaching the roof fixing metal fittings to the columns at the construction site according to the present invention, it is possible to attach a roof of any slope depending on the fixing position of the columns.

Further, in the present invention, if the roof fixing metal fittings are preliminarily attached to the pillars at a factory, the fittings can be attached more reliably and accurately than if they were attached at the construction site.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing a state in which a lower house roof is attached.

In the figure, l is a residential unit on the first floor.

In the figure, a ceiling beam 11 on the gable side, a ceiling beam 12 on the girder side, and a column 13 in the front row, which are part of this first floor housing unit 1, are visible.

The ceiling beam 11 on the gable side and the foldable ceiling beam 12 are made of a C-shaped lightweight steel frame. Further, the pillar 13 is made of a rectangular tube-shaped lightweight steel frame.

2 is a residential unit on the second floor, and residential unit 1 is on the first floor.
It is placed on top of it, shifted backwards.

In the figure, the floor beam 21 on the gable side, the folding floor beam 22, and the pillar 23 in the front row of this second-floor residential unit are visible.

The floor beam 21 on the gable side and the foldable floor beam 22 are made of a C-type lightweight steel frame. Further, the pillar 23 is made of a rectangular tube-shaped lightweight steel frame.

3 is the roof of the lower house, with two frames 31 and 31 in the direction toward the gable side and two frames 3 in the direction toward the folding side.
2.32 forms four circumferences and forms a rectangle. In this, four wooden supports [33, 33, 33, 33] are provided between the frames 32 and 32 in the direction toward folding.

The frame 31.31 facing the gable side and the frame 32.32 facing the folding side are made of C-type lightweight steel frames.

4 is a roof fixing metal fitting attached to the pillar 23 of the housing unit 2 on the second floor.

5 and 6 are frames 32 in the direction toward the folding of the lower roof 3
The top and bottom fasteners are attached to the top and bottom fasteners.

Then, attach this upper fastening metal fitting 5 to the roof fixing metal fitting 4, and
The lower stopper 6 is stacked on the pillar 13 of the housing unit 1 on the first floor, and both are fixed with bolts and nuts to fix the lower house roof 3.

Reference numeral 7 denotes an outer wall support, which closes the gap between the lower house roof 3 and the part where the first floor housing unit 1 protrudes from the second floor housing unit 2.

Next, the assembly method and operation of the embodiment will be explained.

The housing unit 1 on the first floor and the housing unit 2 on the second floor, which have been manufactured in advance at a factory, are installed at the construction site. At that time, 2
The housing unit 2 on the first floor is shifted rearward from the housing unit 1 on the first floor and placed on top of the housing unit 1 on the first floor.

The roof fixing fittings 4 are attached to the pillars 23 of the housing unit 2 on the second floor. The roof fixing fittings 4 may be fixed to the pillars 23 in advance at the factory, or may be attached at the construction site.

If this roof fixing metal fitting 4 is attached to the pillar 23 at the construction site, it can be attached to any position in the middle of the pillar 23, so that the slope of the lower roof 3 can be arbitrarily determined.

Furthermore, if the roof fixing fittings 4 are attached to the pillars 23 in advance at a factory, the slope of the lower house roof 3 is fixed, but since the work can be done at the factory, the lower house roof 3 can be attached accurately and reliably.

Next, the outer wall support 7 is attached to the part where the housing unit 1 on the first floor protrudes from the housing unit on the second floor.

The lower house roof 3, which has been assembled in advance at the factory, is placed on the protrusion of the housing unit 1 on the first floor, and the upper stopper 5 is attached to the roof fixing bracket 4, and the upper stopper 6 is attached to the pillar 13 of the housing unit 1 on the first floor.
Stack them on top of each other and secure them both with bolts and nuts.

After that, the roof base and roofing materials for the lower roof are applied, and the housing unit is finished to complete the assembled housing.

(Effects of the Invention) In the present invention, since the upper floor is placed on top of the housing unit on the lower floor by shifting it backwards, it is only necessary to provide a roof fixing bracket in the middle of the pillar in the front row of the upper floor. , a lower roof can be installed very easily.

With the present invention, the roof fixing metal fittings are installed in the middle of the pillars in the front row of the upper floor.
If the roof fixing metal fittings are attached at the construction site, the roof fixing metal fittings can be installed at any location in the middle of the columns at the construction site, so the roof slope can be arbitrarily determined at the construction site.

Moreover, by doing so, the roof slope can be easily changed by subsequently changing the height of the roof fixing metal fittings.

If the roof fixing metal fittings of the present invention are attached to the pillars in advance at the factory,
The lower M roof can be installed more reliably and accurately than at the construction site, and the number of man-hours required for installing the lower M roof at the construction site is reduced, and the period from installation to completion of the prefabricated house can be shortened.
